Method and system for reducing resource hang

Abstract

The invention provides a method and a system for reducing resource hang. The method comprises that: a media gateway controller receives a response after sending a request of applying for media resources to a media gateway, and if the media gateway controller judges that the response is a response of successfully applying for the media resources and a request of applying for the media resources corresponding to the response does not exist in the media gateway controller, the media gateway controller establishes a request of releasing the media resources according to resource information carried in the response and transmits the request to the media gateway; and the media gateway carries out the operation of releasing the media resources according to the request of releasing the media resources. The method can reduce the occurrence of resource hang conditions on the media gateway, so that the system is operated more stably and highly efficiently.

Description

technical field [0001] The invention relates to the field of communication using the idea of ​​separation of control and bearer to form a network, and in particular to a method and system for reducing resource hangups on bearer network elements. Background technique [0002] With the increasingly wide application of communication systems in various fields such as economy and social life, the communication system technology itself is also developing rapidly, whether it is the third-generation Multimedia Subsystem, IP multimedia system), technological development is increasingly meeting the needs of users for communication systems. At present, the industry generally agrees that the next-generation communication system will be a network in which control and bearer are separated. Its basic feature is to separate the traditional control and call centralized equipment into MGC (Media Gateway Controller, Media Gateway Controller) and MGW ( Media Gateway, media gateway) two parts, ...

Problems solved by technology

[0009] However, this processing method also has certain disadvantages: the media gateway needs to bind timer resources for each resource to perform resource hanging detection, which will occupy a large amount of system resources; the detection of resources on the media gateway needs to Realization of interactive messages between gateway controllers will be triggered at a fixed time interval, which increases the message flow between network elements and also increases the processing load of the media gateway and the media gateway controller; After the hanging, the media gateway controller needs to release it. In this way, it takes a long period for the media gateway to detect that the resource is hanging until the hanging resource is released. However, in the communication system, if the resource cannot be released in time, it will often cause call loss.
